本研究的目的是评估犬的病理性牙齿变化和异常的数量。对139只7月龄至15岁的雄性犬和120只雌性犬的牙科疾病进行了放射学检查。有235只纯种狗和24只杂种狗。对口腔进行临床检查和X线摄影。记录缺牙、牙周炎、牙折和旋转、恒牙和多生牙的发生率和程度。还确定了30%的犬出现一种以上的异常。缺牙发生率为45.17%，牙周炎发生率为44.40%，骨折发生率为19.30%，牙齿旋转发生率为11.59%，恒牙发生率为5.40%，多生牙发生率为3.86%。我们的研究结果表明，不同年龄组的狗之间的牙齿变化和异常的发生率显着不同。牙缺失、牙旋转、乳牙残留、多生牙的发生率以最年轻组最高（p < 0.001），牙折以中年组最高（p < 0.001），牙周炎以中老年组最高（p < 0.001）。考虑到先天性缺牙、牙齿旋转和乳牙残留等异常的遗传性质，犬只繁殖者应及时提供X光检查，并在出现这些异常的情况下，排除受影响的犬只继续繁殖。
The purpose of the present study was to assess the number of pathological dental changes and anomalies in dogs. The incidence of dental diseases was investigated in radiologically examined 139 males dogs and 120 females dogs, aged seven months to 15 years. There were 235 purebred dogs and 24 mongrels. The oral cavity was clinically examined and radiographed. The incidence and extent of oligodontia, periodontitis, dental fractures and rotations, persisting deciduous teeth and supernumerary teeth were recorded. It has also been established that 30% of dogs presented more than one anomaly. The incidence of oligodontia equalled to 45.17%, peridontitis 44.40%, fracture 19.30%, tooth rotation 11.59%, persisting deciduous teeth 5.40% and supernumerary teeth 3.86%. Our results have shown that incidence of dental changes and anomalies differed significantly between dogs of different age groups. The highest incidence of oligodontia, tooth rotation, retained deciduous teeth and supernumerary teeth was observed in the youngest age group (p < 0.001), dental fracture in the mid-age group (p < 0.001) and peridontitis in the mid-age and oldest age group (p < 0.001). Considering the hereditary nature of the anomalies such as congenital oligodontia, tooth rotation and retained deciduous teeth, dog breeders should provide for a timely X-ray examination and, in case of these anomalies, exclude the affected dogs from further breeding.
